"24" fans were ecstatic when FOX
announced it was bringing the show back for a limited-run series.

They were elated Jack Bauer would
return, once more, to save the day.

And, they were, well, curious
about Chloe's new look.

When "24" fans first met Chloe
(Mary Lynn Rajskub) in season three, she was a straight-laced, no-nonsense
computer programmer. Throughout her time on the show, she became a confidant
and friend to Jack Bauer (Kiefer Sutherland). When the series ended, Chloe had
risen to the top of the Counter Terrorism Unit - and in that position, she
turned a blind eye as Jack, wanted by the U.S. government, escaped to freedom.

Now, four years later, on "24:
Live Another Day," Chloe also is on the run. She's joined an underground WikiLeaks-type
hacking outfit and she's gone totally punk rocker. This more somber version of
Chloe is tattooed and pierced with Joan Jett-black hair.

When Rajskub received her first
two scripts, "First of all, when I read them, they were very exciting and read
like classic '24' scripts," she said. "And I kind of hopped up at the ends of
reading two of them and then I was like, 'Wow, I want to know what happens
next.'

"So, that was exciting. And then,
of course, in the description it was a very different Chloe. It was very
briefly and loosely described, and it wasn't until I got to London, and it was
about a week, and the first thing we did was the Super Bowl promo. So, that was
kind of cool, because that got me together with Kiefer and then we kind of came
up with a look that was the first thing we shot.

"So, I met with the hair and
wardrobe and makeup, and we just had a great few days of coming up with this
idea for this character. So, I did it with that team, and then we presented it
to the producers and everybody and sort of took it from there."

Chloe's new wardrobe is
representative of what's happened in her life. She was forced from CTU and
subject to criminal charges because she let Jack flee. Following that, Chloe's
husband and young son were killed in a car crash meant for her, and she lost
track of Jack.

"She is really in a lot of pain,
and kind of just holding on," Rajskub said.

Chloe is reunited with Jack, who rescues her from the London CIA station. The two decide to help save President James Heller (William Devane), even though his government seeks their capture.

"I feel like Chloe this time around has been
more dragged to the dark side, for lack of a better description, where she's
now part of ... trying to always save the world and deal with these
larger-than-life intense situations," Rajskub said.

Fans might be shocked to see this
new version of Chloe. Rajskub, herself, was stunned to learn there would be any version of her character on TV again.
She was surprised to learn FOX was bringing back its Emmy-winning series (and
Chloe, too).

"I was very shocked when I found
out, because I had moved on with my life," Rajskub said. "It had been four
years, and so I spent a few days with my husband and my child and my dogs
walking around (in) my pajamas going, 'What is happening?' Kind of not
believing it and watching my Twitter feed blow up. And I responded, like, 'We're
very excited.' Meanwhile, I was waiting for them to actually pick up the phone
and call and ask me to be involved. And, of course, I said 'yes' without
hesitation. How could I not?"

"I never thought this would come
back," Rajskub said. "It was a once-in-a-lifetime thing that is now twice in a
lifetime."
